OILING 1 Application filed June 23,

To all whom it may (on Cm.

,B 1tknown that l. AnoLrn L. Dr. Lrzniuv,

a citizen of the United States, and residing 1 at Clnclnnatl. 1n thecounty of llan'nlton and State of ()him have invented a new and ImprovedOlllng System. of which the following specification is a full disclosureThis=invention relates to a machine tool oiling system and it proposes aframe organization such that oil will be autonnuically elevated from alowermost well or point to an uppern'iost reservoir. from which it Willbe gravimetrically distributed to the various wearing surfaces. largelyly-mean of conduits integral'with the main casting v or frame of themachine.

A primary object of this invention is to l it i tbs-charged directlyinto the well, and

create a gravimet'rical oil distril'iuting frame in which oil will bekept in continuous circulation throughout all. of lln.- \rearingsurfaces, and will be ultimately (n-ma ia, an

taminated oil added to the/well oil Well and then elevated to an u ipermost dlstrlbutmgpoint, and then led by approprlate channels arrangedin what may he termed parallel series as distinguishcd'from multipleseries, so .that each bearing releases itscontaminated oil lii-e tly ttl1r well, and not to other bearings.

v Heretoforc an oiling system has been proposed in which oil was drawnfrom a well in the frame of the machine and then distributed to anuppermost wearing surface, from which it was released in amore or lesscontaminated condition and caused to pass through another bearing, whichfurther contaminated it, and in turn released it into. another bearing,and so on, until ultimately itwas permitted to return to the oil wellafter having been successively contaminated by passing through severalbearings; \Vhen it reached the oil well it was of course diluted by alarger mass "of oil so that it. was suitable for reapplication' to the.bearings. This system, while not injurious on the first reached bearing,was ol jeetionahle as to sub- 1a 'terreceived oil containing an undueper centage of impurity. drop of highly (win would be so diluted as tobe ha rmlcss so that a drop taken from the well would represent goodlubricating material, but as soon as this "drop passed through the firsthearing it. would be ontamintrtad liy a certain perccntage or iipppt'eanatierv the pcre en age of l i i Specification of Letters Patent.

After the'oil has left.- tlievol-ions wearing: surfaces aforesaid. it flows to the base of the.nmcliine and through in vent 36 to an oil well 37 from Wllllh it israised by the pump ll) as aforesaid.

The vertical spindle ormlnization is shown more vlpnrly by Figs. 3 and1, anti will. now be llesvi'iliml. 'l'hevcolumn -10 of this machinerises from a suitable base'M and tar minutes in a head eliin which isjournnled the i'oi'tival spindle 43 by means of barii -14 and 45. At itsupper end. an annular reservoir 46 is prm'iiled, which discharges theoil by means of an overflow 4? onto a web 48 preferably mistv integral-with the frame. The oil is conveyed to the hearing 44- by means of thegroove 49 lending from the annular reservoir 46, and it'passes down thespindle to the lower bearing f1 which it is'tln-mvn off onto the mainfrail.

ll the oil-ring: 50, and it than flows down the inelinv and ultimatelyto the oil well in the base. lt is to lionoted here that-although inthis instance the oil flows from. the bearing to {he hearing no llrlkilrontnminntion is exprienveil, since the in; 44- carrieshnfllly anylflflll at. all, it ne- 3 ing rolieverl from thrust. in" the hearingtrough? ce io'ni hood t dams 53 and 5% that divert the oil sufficientlyto cause it to flow down small, drain pipes 55, 56 and 57. p The drain55 leads to the forward hearing: 58 of a driving shaft 59, nncl thevpipe 56 leads to the rear heating of after the oil has passed throughthese hearings it drinblos down the. frame of the machine toward thebase and into the oil well. This column. like that of the horizontalspindle. also has :1 similar opening 24 that receives a similartransmis' sion unit 25 containing frame extensions 26 and 97 providingcanals Q9 and 29 from which lead (luctsfil and 32 to the varioushearings of the transmission unit. Thus,

the canal 28 provides'a pool 60,- into which oil is directlv deliveredby the pipe 57 and it then overflows the edge of the pool 60 andpassesdown the canal, being diver-ted at intervals by'means of dams 61 and 62to insure its flow through the ducts 31 to the various bearings, asshown by Fig. 4. The oil overflowingthe canals 28 and 29 and dischargingfrom the various bearings then passesdirec-tly to'the oil Well in thebase.

Leading from a lowerpoint of the web 48 is an overflow pipe 63 thatdischarges into the pool 64 of the speed change insert unit 34, and theoil then flows over the spillway 65 and the successive dams 66 and 67.and finally through the discharge gutter 68 down to the well. Ducts oroil holes 69 lead, to the various bearings of this unit,

and the latter in turn. discharge the contaminated oil to the centralwell, where it is diluted and returned to the system.

It will thus be perceived that this invention is well adapted to achievethe objects aforesaid in a simple and direct manner, and in a waypreventing the admission of unduly contaminated. oil onto any of thebearings.

\Vithoutfurther elaboration, the foregoing will so fully reveal the gistof this invention that others can by applying current knowledge readilyadapt it for various applications without omitting certain featuresthat, from the standpoint-of the prior art. fairly constitute essentialcharacteristics of the generic or specific aspects of this invention,and therefore such adaptations should and are intended to becomprehended within the meaning and range of equivalency of thefollowing claims.
